Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to an armature connecting piece for a flat wire motor. Background Technique

[0002] A flat wire motor generally consists of a motor housing and an armature. The motor housing has an inner cavity, and the armature is inserted through the inner cavity. Generally, a stop is provided at the bottom of the inner cavity at one end of the motor housing. The outer diameter of the stop is basically the same as the inner diameter of the end of the armature. The armature in the flat wire motor is wound with flat wires, and finally the bottom of the armature is inserted on the stop to form a fixation.

[0003] Among them, Chinese Patent (CN221058086U) discloses a motor armature connecting piece, including a machine housing, an end housing, an armature shaft and a limiting member. A limiting ring housing is fixedly penetrated at one end of the machine housing, and a limiting ring is fixedly penetrated at one end of the end housing. And the limiting ring is vertically inserted and assembled in the limiting ring housing. The armature shaft is vertically installed in the machine housing, and the other end of the armature shaft rotates through and is installed on the other end surface of the end housing. The limiting member is arranged inside the end housing, and two limiting members are symmetrically arranged. And the two limiting members are symmetrically supported and sleeved on the armature shaft. The limiting member includes a bearing, and a limiting ring sleeve is fixed on the inner ring wall of the bearing, and the limiting ring sleeve is limited and sleeved on the armature shaft. The utility model overcomes the problem that in the use of existing motors, the armature rotation generates an axial vibration force and lacks an absorption and damping device, and the vibration generated when the armature works is transmitted to the motor, resulting in the loosening of the bolts for installing the limiting member, affecting the stability of the later support and limitation of the armature.

[0004] At present, the motor armature connecting pieces on the market have the same disadvantages as the above-mentioned comparative document: when the armature is installed into the inner part of the housing, the bottom of the armature may contact the inner bottom wall of the housing. When the flat wire motor is opened after installation and use, the rotation of the inner armature may cause friction with the housing, resulting in wear of the bottom of the armature and increasing the temperature during the operation of the flat wire motor, which is likely to reduce the service life of the flat wire motor; for this reason, we have designed an armature connecting piece for a flat wire motor. Content of the Utility Model

[0005] The technical problem solved by the utility model is to provide a flat wire motor armature connecting piece with relatively high practicability, which can be operated simply and has a relatively simple structure, and solves the problem that the rotation of the armature may cause friction with the housing, resulting in wear of the bottom of the armature and increasing the temperature during the operation of the flat wire motor as mentioned in the above background technique.

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions: a flat wire motor armature connecting piece, including a housing and a clamping mechanism assembled inside the housing;

[0007] The housing includes fixing posts and a cover plate fixedly connected to the tops of the fixing posts by bolts. An installation groove is provided inside the fixing posts, and an armature shaft is rotatably connected to the center of the surface of the cover plate through a first bearing;

[0008] The clamping mechanism includes two fixing plates fixedly connected to the bottom wall of the installation groove, a circular ring fixedly connected to one side of the tops of the two fixing plates, and a supporting ring arranged inside the circular ring. A plurality of first rectangular grooves are formed on the surface of the supporting ring. A plurality of second rectangular grooves aligned with the first rectangular grooves are formed on the surface of the circular ring. A plurality of Z-shaped plates are rotatably connected inside the plurality of second rectangular grooves. One ends of the plurality of Z-shaped plates are rotatably connected to both sides of the first rectangular grooves. A plurality of springs are fixedly connected to the bottom of the supporting ring. A plurality of buffer rods are sleeved inside the plurality of springs and fixedly connected to the inner bottom wall of the installation groove.

[0009] Optionally, two sliding grooves are formed on opposite sides of the two fixing plates, and two limiting blocks are slidably connected inside the two sliding grooves.

[0010] Optionally, one sides of the two limiting blocks are fixedly connected to both sides of the supporting ring, and a clamping groove is formed on the top of the supporting ring.

[0011] Optionally, the armature shaft is rotatably connected to the surface of the clamping groove through a second bearing, and a circular hole is reserved at the center of the clamping groove for the bottom of the armature shaft to pass through.

[0012] Optionally, heat dissipation fins are arranged in a circumferential array on the surface of the fixing posts, and fillets are arranged on the surfaces of the heat dissipation fins.

[0013] The utility model provides a flat wire motor armature connecting piece, which has the following beneficial effects:

[0014] For this flat wire motor armature connecting piece, through the setting of the clamping mechanism, one end of the armature shaft with the second bearing is inserted into the clamping groove on the surface of the supporting ring, and then the armature shaft is pressed down to squeeze the spring, thereby driving both sides of the supporting ring to slide down in the sliding grooves of the fixing posts, and then driving the end of the Z-shaped plate rotatably connected to the supporting ring to move downward. The other end rotatably connected to the circular ring remains stationary up and down, thereby driving the top of the Z-shaped plate to approach the second bearing and clamping the second bearing. Finally, the cover plate is installed on the surface of the first bearing, and then the bolts are tightened to fix the cover plate on the top of the fixing posts, ensuring that the bottom of the armature shaft does not contact the inner wall of the installation groove of the fixing posts, reducing the friction between the armature shaft and the fixing posts during rotation. At the same time, if axial vibration occurs during the rotation of the armature shaft, the spring can absorb part of it, reducing the vibration generated during the operation of the flat wire motor.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 4, the present utility model provides a technical solution: a flat wire motor armature connector, which includes a housing 1 and a clamping mechanism 2 assembled inside the housing 1. The housing 1 includes a fixed column 101 and a cover plate 103 fixedly connected to the top of the fixed column 101 through a bolt 102. An installation groove is provided inside the fixed column 101. A first bearing 104 is rotatably connected to an armature shaft 105 at the center of the surface of the cover plate 103. The clamping mechanism 2 includes two fixing plates 201 fixedly connected to the bottom wall of the installation groove and a circular ring 202 fixedly connected to one side of the tops of the two fixing plates 201, and a supporting ring 203 mounted inside the circular ring 202. A plurality of first rectangular grooves 204 are formed on the surface of the supporting ring 203, and a plurality of second rectangular grooves 205 aligned with the first rectangular grooves 204 are formed on the surface of the circular ring 202. A plurality of Z-shaped plates 206 are rotatably connected inside the plurality of second rectangular grooves 205. One end of each of the plurality of Z-shaped plates 206 is rotatably connected to both sides of the first rectangular groove 204. A plurality of springs 207 are fixedly connected to the bottom of the supporting ring 203. A plurality of buffer rods are sleeved inside the plurality of springs 207 and fixedly connected to the inner bottom wall of the installation groove. One end of the armature shaft 105 with a second bearing 106 is inserted into a clamping groove 210 on the surface of the supporting ring 203, and then the armature shaft 105 is pressed downward to squeeze the springs 207, thereby driving both sides of the supporting ring 203 to slide downward in a sliding groove 208 of the fixed column 101, and further driving one end of the Z-shaped plate 206 rotatably connected to the supporting ring 203 to move downward, while the other end rotatably connected to the circular ring 202 remains stationary up and down, thereby driving the top of the Z-shaped plate 206 to approach the second bearing 106 and clamp the second bearing 106. Finally, the cover plate 103 is installed on the surface of the first bearing 104, and then the bolt 102 is tightened to fix the cover plate 103 on the top of the fixed column 101, so that the bottom of the armature shaft 105 does not contact the inner wall of the installation groove of the fixed column 101, reducing the friction between the armature shaft 105 and the fixed column 101 during rotation. At the same time, if axial vibration occurs during the rotation of the armature shaft 105, the springs 207 can absorb a part of it, reducing the vibration generated during the operation of the flat wire motor.

[0022] Further, two sliding grooves 208 are formed on the opposite surfaces of the two fixing plates 201, and two limiting blocks 209 are slidably connected inside the two sliding grooves 208. Among them, the sliding of the limiting blocks 209 inside the sliding grooves 208 enables the supporting ring 203 to move only vertically up and down and is difficult to deviate.

[0023] Further, one side of each of the two limiting blocks 209 is fixedly connected to both sides of the supporting ring 203, and a clamping groove 210 is formed on the top of the supporting ring 203. Among them, the clamping groove 210 facilitates the insertion of one end of the armature shaft 105 with a second bearing 106 onto the supporting ring 203.

[0024] Furthermore, the surface of the card slot 210 is rotatably connected to the armature shaft 105 through a second bearing 106. A round hole is reserved at the center of the card slot 210 for the bottom of the armature shaft 105 to pass through. When the armature shaft 105 generates axial vibration during operation, one end of the armature shaft 105 will move within the round hole on the surface of the retaining ring 203. Furthermore, the spring 207 will absorb a part of the vibration potential energy, reducing the axial vibration generated during the operation of the armature shaft 105.

[0025] Furthermore, heat dissipation fins 3 are circumferentially arrayed on the surface of the fixing column 101, and rounded corners are provided on the surfaces of the heat dissipation fins 3. Among them, the heat dissipation fins 3 can help the device dissipate heat.

[0026] In the present utility model, the working steps of the device are as follows:

[0027] Install the end of the armature shaft 105 with the first bearing 104 on the cover plate 103. Insert the end of the armature shaft 105 with the second bearing 106 into the card slot 210 on the surface of the retaining ring 203. Then press down the armature shaft 105 to compress the spring 207, thereby driving both sides of the retaining ring 203 to slide downward in the sliding grooves 208 of the fixing column 101. Furthermore, drive the end of the Z-shaped plate 206 rotatably connected to the retaining ring 203 to move downward, and the other end rotatably connected to the ring 202 will remain stationary in the up and down direction. Furthermore, drive the top of the Z-shaped plate 206 to approach the second bearing 106 and clamp the second bearing 106. Finally, screw in the bolt 102 to fix the cover plate 103 on the top of the fixing column 101 to complete the installation.
